[qdkedsco] Thwarting the evil maid

Preventing physical attacks against unattended computers carrying valuable data is simply the problem of physical security, e.g., safes and locks, which has been studied for a very long time, though this is a new form factor.

Desired features: A laptop which can be locked closed with a lock (maybe padlock) of the user's choosing so that the user can balance security versus convenience.  Laptop cannot be disassembled while locked.  Ports cannot be accessed while locked.

Some users may want tamper-proof physical security; others may just want tamper-evident physical security.  Tamper-evident can interface with the computer to record and notify attempts at tampering.
